Forth time around. This time they replaced the back 4 bolts with the "special bolts & washers". The manager was getting tired of seeing me I guess and had it done within an hour.

Another exhaust manifold bolt broke. This time it was the front one and the jeep in now under warranty anymore. Paid $8 for one bolt and washer to fix it.

took jeep in for a third time to get rear manifold bolt replaced. This time they had to send the head out to get it machined and it would take 5 days. Told them I was getting tired of this B.S. The manager said that they have new improved bolts with special washers so that this wouldn't happen again. So I let them take my jeep. I should have known better.

Guess what? more broken exhaust manifold bolts. This time the dealership sold me new and improved bolts as opposed to the new and improved bolts I bought last time. These have a star head, locking nut, and more of those special concave washers.

replaced rear bolt on manifold again. this is the second time.

Heard popping sound from engine. Dealership fixed it under warranty. Rear exhaust manifold bolt broke.
